Since we know Zack will have to pay 11.00 dollars per every 100 dollars each month, we just need to divide the amount that Zack borrowed by 100 dollars, and then multiply the result by 11.00 dollars:
[tex] \frac{1087}{100} =10.87[/tex]
Know we know that Zack will have to pay 11.00 dollars 10.87 times each month, so we just need to multiply both quantities to find his monthly payment:
[tex]11.00*10.87=119.57[/tex] dollars
We can conclude that Zack's monthly payment will be $119.57
